    Abstract:
    PROBLEM: To evaluate the role of regulatory T (Treg) cells in autoimmune ovarian disease (AOD). METHOD OF STUDY: AOD model was set up by thymectomy of BALB/C mice on day 3 (d3tx). The variation of T lymphocyte subsets, especially the Treg cells were analyzed in the peripheral blood, spleen, para-aortic, and inguinal lymph nodes in d3tx mice. The effect of Treg cells on AOD was further evaluated by adoptive transfer of Treg cells into d3tx mice (d3tx+Treg). RESULTS: In d3tx mice, the ratio of Treg/CD4+ was significantly increased rapidly from 1st to 2nd week, rapidly declined in 3rd week, then decreased slowly until the 9th week. The CD3+ /T lymphocytes and the ratio of CD4+ /CD3+ were significantly decreased in the para-aortic and inguinal lymph nodes of d3tx mice, but the ratio of Treg/CD4+ and CD8+ /CD3+ were increased simultaneously. In d3tx mice with adoptive transfer of Treg cells (0.5×104 ~5×105 ), there was a significant increase in the Treg/CD4+ ratios in the spleen and peripheral blood. AOD score, especially adoptive transferred treg cells from the ovarian lymph nodes was significantly decreased. Oocytes were successfully obtained from d3tx+Treg mice, which could fertilize and develop to embryos normally. CONCLUSION: Treg cells involved in the pathogenesis of AOD. Sufficient numbers of Treg cells can modify AOD in the early phase in d3tx mice.
